Doh - it was an owner/permissions problem again. The RRD files were
owner root:root instead of ${WWWUSER}:${WWWGROUP} or perhaps better
${USER}:${WWWGROUP}. Permissions were 644 (others are 664). I have a
feeling that the correct permissions/owner should be:
${USER}:${WWWGROUP} 644

Anyway, RRDs are updating and graphs are working now. Looks like another
little tweak to the nfsen script.

Cheers
